The fragile nature of MMPI code types.
The percent of code type agreement with the original MMPI is compared with the new MMPI-2, an earlier re-norming of the MMPI by Colligan, Osborne, Swenson, and Offord (1983), the MMPI-168, and test/retest comparisons of the MMPI with itself. Code type agreement ranges from lows of 31 to 41% for the test/retest comparability of the original MMPI with itself to 40 to 67% hit rates for the MMPI-2, the MMPI 1983 norms, and the MMPI-168. The effect of this on interpretation is discussed in the context of previous studies on the MMPI code types in relation to broadband diagnosis and comparisons of clinical accuracy of computerized reports that have utilized various MMPI versions.
